Thanks for the link. This looks to be sufficient confirmation for my
requirements - if a vendor/admin somewhere decides not to adhere to the
specification then I don't think that this can be held as my
responsibility.

I'll just double-check the browser caching side of things now - thanks
to you and Volkan for your help.

I haven't been on this list for a while - it's nice to be back.

Cheers!
